We've been running into this for months, mainly on the kids' channels (Teletoon, etc.). We'll watch an episode of a show. The kids will like it, so we'll set up a series recording on the PVR. Come back a few days later to watch the recorded episodes, and see that they're all for a different program than the one we set up the recording for. The List on the PVR says one show, with description, time, etc. When we play it, the actual show is completely different.
This is now happening on about half the kids shows we try to PVR (the latest is Adventure Time - turned out to be a bunch of Scooby Doo episodes). Very frustrating. Anyone else noticing this? Is it a known issue?
